Whether its a mid-day picnic or an at-home concert under the stars, the Bose® 151® SE outdoor speakers deliver the full stereo sound you want. Youll enjoy the same rich sound of music grilling on the porch or doing a little gardening around the backyard. Inside each speaker are three 2½-inch full-range environmental drivers arranged in an Articulated Array speaker design. This provides Stereo Everywhere speaker performance for consistent sound in a much wider area than conventional speakers provide. You have the freedom to listen to your music wherever you are, not just in a small sweet spot where your music sounds best. For more than ten years, Bose outdoor speakers have stood up to some of natures worst conditions. Theyve been tested against snow, rain, salt and temperature extremes of 158º F (70ºC) to -40º F (-40ºC). We even put them through 1,200 hours of salt-fog testing, which is twice the demanding Marine Industry Standard. And to further underline their toughness, we added a five-year transferable limited warranty. Outdoor speakers should reflect the same attention to detail you like throughout your home. Bose 151 SE speakers are designed to blend smoothly with horizontal eave, clapboard and roof lines. Sleek, compact cabinets accentuate your outdoor environment instead of imposing on it. New adjustable, weather-resistant brackets allow you to hang the speakers vertically or horizontally, depending on your preference.
